With last week’s release of baseball’s Mitchell Report, as well as suggestions for improving the game, it's a good time to take a look at mixed martial arts and how to combat performance enhancing drugs.

Im shocked about Andy Pettite. All fighters tested clean at UFC 78 which I was very happy with. It gives hope that fighters realize it's cheating. Each fight is so important and is a "make you or break you" so I understand why fighters want to have an edge going into it.
